PROBLEM TO BE SOLVED: To provide an apparatus for generating microbubbles, which allows an improvement in white turbidity by drastically increasing the amount of microbubbles to be generated. SOLUTION: The apparatus for generating microbubbles is characterized in that an air-dissolved aqueous fluid with air dissolved under pressure, in the water, is discharged from a discharge nozzle 30 by releasing the pressure of the air-dissolved aqueous fluid by a decompression means 12 while generating microbubbles. An ejector 52 for introducing air is arranged on a water supply line for supplying water to an air dissolution unit 8 for dissolving air in water under pressure. An edge 52d is formed on the downstream side of an air outlet portion 52c, where an air introduction port 52a of the ejector 52 and the water supply line 52b of the ejector 52 are made to cross each other, in the water flow direction at the least.
